Determine the substitution if-

Answer 1

$<h4>3 ). ( a ). Putting - 2 at the place of x, 5x = 10 5 ( - 2 ) = 10 -10 = 10 L. H. S. ≠ R. H. S.$

$<h4>-2 is not the root of 5x = 10.$

( b ). Putting - 5 at the place of x,

x - 5= 0

-5 - 5 = 0

-10 = 0

So, L. H.S. ≠ R. H. S.

$<h4>-5 is not the root of x - 5 = 0$

( c ). Putting value of 2 at the place of x,

x^3 - 8 = 0

2^3 - 8 = 0

8 - 8 = 0

0 = 0

L.H.S. = R. H. S.

$<h4>So, 2 is the root of x^3 - 8 = 0.$
